HELP Htc one att phone lots of problems !!

please read the bottom part of what i wrote in the thread ,, basically i went back to 4.3 and it worked and fixed the mms but it took away my 4g so i thought it was easy enough lets try the 4.4 version of that rom and maybe have the bes tof both worlds and now as u read i cant do anything , but get into bootloader but anything i try goes back to a frozen htc screen , it will go to recovery it will show cwm for a few seconds go blank and back to htc screen frozen , i cant sync to the computer , but i can power down and charge it please help , thanks so much for the help

ok ive been working on it all night and morning long , so here is what i have now , i managed to get twrp working , problem is i think that last one wiped out everything it says no OS to reboot and i cant get it to recongnize device on my computer , i have everything saved in my harddrive just in case i needed to got back but i cant get it to recongnize it on my computer but twrp all works and i can navigate on it and fastboot usb is working cause twrp got put on ,, now how to install all the saved OS back on the phone via twrp or fastboot usb is the question?

im going to use this to help other noobs like myself that gets courageous enough to try rooting , customer roms unlocking etc. seems easy to the tech guys but some of the lingo is not so easy and u can make one bad move , i hope i didnt

at any rate here is where im at , i did get twrp setup in fastboot mode so all i have is fastboot mode to do anything atm ,, it appears like i said i somehow wiped my whole operating system , how i dont know but i have one more thing i think from the help of others may work and that is use a micro usb otg cable to hopefully flash the rom back on the phone , wish me luck , unfortunately im not sure locally where to buy one , i will go look this evening , but in the meantime i did order one for a couple of bucks on ebay just in case i couldnt find one locally , i will update

Boot into boot loader and flash RUU that matches your cid as I take it your s-on still.
Do not flash anything does. Not match your cid in your case Att = CWS__001

why cant you hook it up to a computer? i see that your getting fastboot and TWRP? if you can get either you should be able to sideload from the computer what you need to boot up again.

if you only have fastboot. then load TWRP via fastboot and then from TWRP, use sideload/command prompt to pump a rom on and then voila you should be good. if you already have TWRP just start from there..
